I copied this off of the Texas method wiki. I wanted to ask what the assistance parts meant. Do press and bench alternate weekly? For press assistance can I use klokov? And for bench can I use close grip? An are they just lighter sets?

All of your main lifts are pretty high intensity with regards to the % 1rm.

Power cleans should be first in the workout, always. What are you using them for? WRT to powerlifting, I can see their use as a Type II warm up for deads or squats, especially front squats. The way you have then programmed is as an accessory movement, which they certainly are not, and you will get more out of the rows.

What is your movement speed for the different lifts on different days?

Do you mean that power cleans should be a primary exercise? I've always used them as an accessory lift for shoulder pre-hab and never went heavy (6-8 reps usually), so my question is, do you advocate going heavy and periodizing gains?

Olympic lifts have a huge speed and technical aspect to them which, in my opinion, makes them fairly dangerous under fatigued conditions. I, and most who have done weighlifting, will propose using them for low reps, using greater amount of sets to add volume and yes periodizing them. All too often, form detriorates which can lead to injury.

Yes, they should be a primary exercise if your goal is to use them for power. You can also use them with lighter loads at the start to a lower body workout as [art of the specific warm up. Either way, doing them fatigued is a recipe for disaster.
